Question

我在Linux Ubuntu 12.04上使用Netbeans 7.2.1，开发Web应用程序，使用spring 3.1.0.RELEASE，spring 3.1.0。 / hibernate，mavenized。我使用公司私人SVN来访问这个项目。打开项目后，我使用build with dependencies，然后清理并构建，然后在apache-tomcat-7.0.41上运行项目，然后是这篇文章末尾的例外。

我尝试了以下内容：

从apache取消部署项目，然后重新部署
重启tomcat
杀死tomcat进程
删除了tomcat，然后重新下载并使用了另一个目标文件夹
删除了netbeans缓存
在本地删除项目并重新连接到相同的svn并重新检查svn。
删除了本地maven存储库，重新下载了jar，同样的异常！
尝试在netbeans 7.3上发生同样的问题。

通知

同一个项目在另一台机器上“完美运行”！
这个问题发生在：
- 我从SVN“A”获得了网络应用“X”，我正在开发网络应用“X”，正在运行，一切都很完美。
- 我在同一个SVN“A”上连接并获得另一个网络应用程序“Y”，问题发生了，并且发生在使用相同步骤的另一台工作中。
- webapp“y”在某些工作机器上运行完美（也用于SVN结账）。

我只是想知道这个问题是什么，问题所在。
